The cross reference of related application
This application claims the right of priority of the European application EP 12306621.9 submitted on December 19th, 2012, the full content for all object this application is combined in this by reference.
Technical field
The present invention relates to a kind of method for the manufacture of sulfone polymer film.Particularly, the present invention relates to a kind of method comprising some sulfone polymer solution of use.
Background technology
There is the aromatic series sulfone of sulfobenzide group as the part of their backbone repeat unit of contraposition connection, be an analog thermoplastic polymkeric substance, it is characterized in that high glass-transition temperature, good physical strength and rigidity and outstanding thermotolerance and scale resistance.By means of its machinery, heat and other make us the performance of wishing, these polymkeric substance enjoy more and more broader and diversified commercial applications scope, comprise the coating for widely using field and film significantly.
Manufacturing technology for industrial film is usually included in prepares sulfone polymer solution in a suitable solvent.According to these technology, a kind of transparent polymers soln is precipitated as two phases: i.e. a kind of phase forming the solid-state rich in polymers of membrane matrix, and a kind of phase forming the poor polymkeric substance of the liquid state of fenestra.Polymkeric substance precipitates and can realize in some modes from solution, such as cools, solvent evaporates, by being immersed in the water precipitation or planar water from gas phase.If precipitation rapidly, then to trend towards film that is less and that formed asymmetric significantly for pore-forming drop.If precipitation slowly, then pore-forming drop trends towards poly-attached and curtain coating liquid still for liquid, makes that final hole is relatively large like this and membrane structure is more symmetrical.
In these techniques, but provide stable and uniform polymers soln remains crucial as parent material.
Most aromatic series sulfuryl polymkeric substance can be soluble in some high polar solvent with some chlorinated solvent to form stable solution.These potent solvents comprise N-Methyl pyrrolidone (NMP), N,N-dimethylacetamide (DMAc), pyridine and aniline, vinyl trichloride and sym.-tetrachloroethane.
Pyridine, aniline and chlorinated solvent are more undesirable, because their potential harmful healthy effects.
About NMP and DMAc, they for many years in the manufacture of polysulfones asymmetric membrane for based on being the solvent selected in industry in the hollow fiber spinning method of solution always, these solvents face environment and safety problem now, consider the security risk relevant to its process and possible leakage/discharge in the environment, so explore alternative scheme.
